What is it about?
This article deals with magnetic nanofluids, which is the part of transformer oil ITO 100 and their behavior is influenced by a permanent magnetic field. The main objective was to examine changes in the properties of the samples due to the influence of the electromagnetic field.

Why is it important?
In this experiment, three samples of magnetic fluids were used. To determine the state of liquid, PDC analyses were executed in the time domain. Individual samples were measured before and after the irradiation with the electromagnetic field. Experiments showed that electromagnetic radiation at a frequency of 900 MHz and power of 30 W had a negative influence on the magnetic fluids. It can also be explained by the fact that can be changed structures of the nanoparticles in the sample exposed to the magnetic field. Also, these processes change the polarization of the liquid because the nanoparticles are contained in the fluid.
Perspectives
I hope this publication will bring people and researchers with new knowledge that they can further utilize and upgrade.
